Description

治疗脑积水用可降解防堵塞脑室分流管
（一）      技术领域
    本发明涉及脑积水治疗领域，特别涉及一种治疗脑积水用可降解防堵塞脑室分流管。
（二）      背景技术
    目前临床上在进行治疗脑积水的疾病时，经常出现的并发症就是分流管堵塞，目前的处理方法只能拔除分流管将其更换，在拔除及更换分流管的时候会产生脑出血或脑损伤的风险，而现在的分流管堵塞问题比较严重，周期比较短，一般手术后一年左右即有40%-50%的病人出现堵管问题，使更换分流管比较频繁，对病人造成脑出血或脑损伤的几率增大，不利于对病人进行治疗。
（三）      发明内容
    本发明为了弥补现有技术的缺陷，提供了一种降低分流管堵塞发生率的治疗脑积水用可降解防堵塞脑室分流管。
本发明是通过如下技术方案实现的：
一种治疗脑积水用可降解防堵塞脑室分流管，包括分流管管身，分流管管身前端侧壁设有出水孔，其特征是：分流管管身前端分体式连接有一降解端头，降解端头的材料为生物可降解材料。
该治疗脑积水用可降解防堵塞脑室分流管，分流管管身前端侧壁设有多个隐藏出水孔，隐藏出水孔表面涂敷有一层可降解涂层，可降解涂层的材料为生物可降解材料，可降解涂层还可以避免由于出水孔过多在插管时造成脑出血或脑损伤的风险。可降解涂层的涂敷方向为横向或纵向。降解端头与分流管管身相插接或通过螺纹相连接。
该治疗脑积水用可降解防堵塞脑室分流管，通过在现有分流管基础上增设由生物可降解材料制成的降解端头和可降解涂层，达到了分流管防堵塞的目的，使分流管的堵塞时间延长，解决了现在脑积水分流管易堵塞的医学难题。所采用的生物可降解材料可选用聚乳酸类材料、聚乙醇酸类材料及其共聚物等。如聚乳酸在体内的降解主要是以酯键的非酶性水解方式进行，其中间产物是乳酸（糖的代谢产物），而乳酸可以进入人体代谢的三羧酸循环，最终代谢成水和二氧化碳，经呼吸道、尿液、皮肤等以各种形式排出体外。
本发明的有益效果是：该治疗脑积水用可降解防堵塞脑室分流管，结构简单，可有效降低分流管堵塞发生率或延长分流管堵塞周期，避免了频繁更换分流管造成的脑出血或脑损伤的风险，利于对病人进行治疗，具有很大的临床推广价值。
（四）      附图说明
下面结合附图对本发明作进一步的说明。
附图1为本发明治疗脑积水用可降解防堵塞脑室分流管的结构示意图。
附图2为本发明可降解涂层纵向涂敷的结构示意图。
图中，1分流管管身，2降解端头，3出水孔，4隐藏出水孔，5可降解涂层。
（五）      具体实施方式
附图为本发明的一种具体实施例。该治疗脑积水用可降解防堵塞脑室分流管，包括分流管管身1，分流管管身1前端侧壁设有出水孔3，其特征是：分流管管身1前端分体式连接有一降解端头2，降解端头2的材料为生物可降解材料。分流管管身1前端侧壁设有多个隐藏出水孔4，隐藏出水孔4表面涂敷有一层可降解涂层5，可降解涂层5的材料为生物可降解材料。可降解涂层5的涂敷方向为横向或纵向。降解端头2与分流管管身1相插接或通过螺纹相连接。
该治疗脑积水用可降解防堵塞脑室分流管,在置管时与普通的分流管使用方法相同，当置管成功以后，降解端头2以及可降解涂层5可以在人体内慢慢降解被吸收，最终会使分流管管身1最前端为敞口状，而且分流管管身1侧壁的隐藏出水孔4敞开，使出水孔数量增多，能有效防止分流管堵塞，延长分流管堵塞周期，降低分流管堵塞发生率，从而避免了在更换分流管时对病人造成的手术风险。
